The c.722T>C (p.V241A) alteration is located in exon 4 (coding exon 3) of the STEAP1B gene. This alteration results from a T to C substitution at nucleotide position 722, causing the valine (V) at amino acid position 241 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
